The Homeland Security Department’s appropriations for the coming fiscal year could be reduced–in many cases significantly–under the House Appropriations Committee’s markup of the department’s annual appropriations bill.

The appropriations’ committee markup, which was on the House floor June 1 with debate and votes on proposed amendments continuing until 12:30 a.m., would give DHS $40.6 billion in base funding for fiscal 2012. That’s about $3 billion less than the president’s budget request and $1.1 billion less than DHS received in the current year for base operations.

The committee would also allocate an additional $258.3 million for “global war on terrorism” operations conducted by the Coast Guard. Federal fiscal years begin each Oct. 1; we are in late in the third quarter of fiscal 2011.

Among the amendments reportedly approved the evening of June 1 were several that would cut additional funds for the office of secretary and other headquarters functions and apply those amounts to grants and other operational programs. The numbers we report below all come from the appropriations committee mark and don’t take into account further possible reductions made on the House floor.
